STS-79 Mission Control Center Status Report #15 Monday, September 23, 1996, 7:30 a.m. CDT The Atlantis and Mir crews bid one another an emotional farewell early this morning and then closed the hatches between their two spacecraft in preparation for this evening's undocking. Shortly before 5 a.m. central time today, the nine astronauts and cosmonauts gathered in the Core Module of the Russian space station for a formal goodbye. With the official ceremony complete, the crewmembers shared a final meal together and exchanged private farewells as Shannon Lucid prepared to return home in Atlantis and her replacement on Mir, John Blaha, began a four month stay on the outpost. Shortly after 7 a.m. today, Mission Specialists Carl Walz and Jay Apt and Mir 22 Commander Valery Korzun with assistance from Flight Engineer 2 John Blaha, swung the hatches between their spacecraft closed concluding five days of joint operations. The vestibule between Atlantis and Mir was depressurized and leak checks were performed in readiness for undocking, which is planned at 8:33 p.m. today. Atlantis/Mir will remain linked during an abbreviated six-hour sleep period for the crewmembers which begins at 12:54 p.m. today. A wake-up call from Mission Control is expected at 6:54 p.m. when the crew quickly step into the undocking timeline. Shortly after 10:30 p.m., Commander Bill Readdy will fire Atlantis' engines in a separation burn to move away from Mir for the final time until Atlantis' return to the station in January. The final day of joint operations began shortly after 9 p.m. Sunday with the crews completing final transfer activities and verifying the inventory lists of materials. More than a ton of water was transferred to Mir, along with logistical supplies, food and scientific hardware. Early this morning the combined crews also took time to discuss their mission with reporters in the U.S. and Russia during an in-flight crew news conference. Atlantis is in excellent condition, circling the Earth still docked with the Mir in a 243 by 230 statute mile orbit. The next STS-79 status report will be issued at 5 p.m. Central time this afternoon. ### NASA Johnson Space Center Mission Status Reports and other information are available automatically by sending an Internet electronic mail message to jscnews-request@listserver.jsc.nasa.gov.
